On each roof you have an exhaust vent to move the hot air out in the summer and the moist air out in the winter. Your roof has to breathe. But if your roof was installed with plastic can vents, you might find them to be the cause of major leaks during a heavy storm in Portland.
Last week I was on top of a roof that had a leak. The homeowner was at his wit’s end. He had no idea where it was coming from. Lo and behold, he had plastic can vents. They were really old and the UV had already attacked the plastic and made them incredibly brittle. I found a long crack on the edge of the can vent that was allowing water to rush right in.
The homeowner was confused. Everyone knows that UV attacks plastic. So why was it being used on his roof? That’s a good question. Unfortunately, many homebuilders these days are just trying to bang out as many roofs as they can, as fast as they can. That usually results in cheap materials and cheap components, like plastic can vents.
Fortunately, Roof Life of Oregon knows to use metal can vents. They last the lifetime of the roof and are going to keep the water out. It’s just a matter of removing a few shingles, popping out the old plastic can vent, replacing it with metal, and you’re good to go.
It’s an easy fix, but in those crisis situations, you’ll be glad your home has metal can vents to keep the water out.
